CHECKING THE PISTON PIN
1. Check:
•
piston pin
Blue discoloration/grooves
Replace the
piston pin and then check the lubrication
system.
2. Measure:
•
piston pin outside diameter
Out of specification
Replace the piston
pin.
Piston pin outside diameter
16.994~17.000 mm
(0.6691~0.6693 in)
<Limit>: 16.960 mm (0.6677 in)
3. Measure:
•
piston pin bore diameter
Out of specification
Replace the piston.
4. Calculate:
•
piston-pin-to-piston-pin-bore clearance
Out of specification
Replace the piston
pin and piston as a set.
Piston pin bore diameter
17.002~17.008 mm
(0.6694~0.6696 in)
<Limit>: 17.020 mm (0.671 in)
Piston-pin-to-piston-pin-bore clearance =
Piston pin bore diameter
Piston pin outside diameter
Piston-pin-to-piston clearance
0.002 ~ 0.014 mm
(0.0001 ~ 0.0006 in)
